ORE Studio is a graphical wrapper around Acadia's Open Source Risk Engine (ORE), which itself is built on top of QuantLib. This open-source project has no affiliation whatsoever with Acadia, ORE, or QuantLib.

Overview

Understanding ORE Studio requires at least a basic familiarity with both QuantLib and ORE. The following summaries are taken directly from their own project descriptions.

QuantLib

QuantLib describes itself as:

‍The QuantLib project (https://www.quantlib.org) is aimed at providing a comprehensive software framework for quantitative finance. QuantLib is a free/open-source library for modeling, trading, and risk management in real-life.

Open Source Risk Engine (ORE)

ORE provides the following description:

‍The Open Source Risk project (https://www.opensourcerisk.org) aims at establishing a transparent peer-reviewed framework for pricing and risk analysis that can serve as:

a benchmarking, validation, training, teaching reference

an extensible foundation for tailored risk solutions

Open Source Risk Engine (ORE) provides:

contemporary risk analytics and value adjustments (XVAs)

interfaces for trade/market data and system configuration (API and XML)

simple application launchers in Excel, LibreOffice, Python, Jupyter

various examples demonstrating typical use cases

comprehensive test suites

ORE is based on QuantLib and extends it with simulation models, financial instruments, and pricing engines.

ORE Studio Goals

ORE Studio extends ORE with additional capabilities:

Persistent Storage: PostgreSQL database with temporal versioning for inputs and outputs, supporting full CRUD operations
Graphical Interface: Qt 6-based desktop application with MDI interface for visual data creation and exploration
Import/Export: Command-line tools for bulk operations with JSON, XML, and CSV formats
Client-Server Architecture: SSL/TLS secured binary protocol for multi-client access
Orchestration Tools: Configuration and execution management for ORE workflows

Architecture

ORE Studio is a C++23 application built on a layered architecture. The system is organized into nine components across five layers:

Foundation: ores.utility (database, logging, filesystem utilities)
Infrastructure: ores.comms (client-server protocol), ores.testing (test infrastructure)
Domain: ores.risk (ORE domain model), ores.accounts (user management)
Application: ores.cli (command-line tool), ores.qt (GUI), ores.service (server), ores.client (REPL command-line client)

For a visual representation of the system architecture and component dependencies, see the system diagram at projects/modeling/ores.puml. Each component has its own class diagram showing detailed internal structure.

For architectural details, see the ores namespace documentation.

Key Features

Data Management

Quick Start

Explore Components

Start with these key namespaces:

ores::risk - Core ORE domain types (currencies, etc.)
ores::accounts - User account management and authentication
ores::comms - Client-server communication protocol
ores::qt - Qt GUI application components
ores::utility - Foundation utilities (database, logging, etc.)
